The Sequent Calculus Trainer with Automated Reasoning - Helping Students to Find Proofs [PDF]
The sequent calculus is a formalism for proving validity of statements formulated in First-Order Logic. It is routinely used in computer science modules on mathematical logic.

A sequent calculus with dependent types for classical arithmetic [PDF]
In a recent paper [11], Herbelin developed dPAω, a calculus in which constructive proofs for the axioms of countable and dependent choices could be derived via the encoding of a proof of countable universal quantification as a stream of it components ...

A Sequent Calculus for a Semi-Associative Law [PDF]
We introduce a sequent calculus with a simple restriction of Lambek's product rules that precisely captures the classical Tamari order, i.e., the partial order on fully-bracketed words (equivalently, binary trees) induced by a semi-associative law ...

A Cut-Free Sequent Calculus for Defeasible Erotetic Inferences [PDF]
In recent years, the effort to formalize erotetic inferences—i.e., inferences to and from questions—has become a central concern for those working in erotetic logic. However, few have sought to formulate a proof theory for these inferences.

Integrating a Global Induction Mechanism into a Sequent Calculus [PDF]
Most interesting proofs in mathematics contain an inductive argument which requires an extension of the LK-calculus to formalize. The most commonly used calculi contain a separate rule or axiom which reduces the important proof theoretic properties of ...

The Sequent Calculus of Skew Monoidal Categories
Szlachanyi's skew monoidal categories are a well-motivated variation of monoidal categories in which the unitors and associator are not required to be natural isomorphisms, but merely natural transformations in a particular direction.

A Classical Sequent Calculus with Dependent Types
Dependent types are a key feature of the proof assistants based on the Curry-Howard isomorphism. It is well known that this correspondence can be extended to classical logic by enriching the language of proofs with control operators.

Verifying a Sequent Calculus Prover for First-Order Logic with Functions in Isabelle/HOL
We describe the design, implementation and verification of an automated theorem prover for first-order logic with functions. The proof search procedure is based on sequent calculus and we formally verify its soundness and completeness in Isabelle/HOL ...

ABSTRACT Neuroblastoma is the most common extracranial solid tumor in early childhood. Its clinical behavior is highly variable, ranging from spontaneous regression to fatal outcome despite intensive treatment.
